This is the Grappa, a dual-purpose shopping bag/emergency helmet that's just as ready to carry groceries as it is to be worn on your head while you run down the street screaming the sky is falling. It was designed with a reinforced bottom for use during natural disasters in case things are falling and you don't want them crushing your precious nog. Me? I carry a pasta strainer for the same purpose but with the added benefit of looking cool. Besides, what shopping bag DOESN'T double as an emergency helmet? "I dunno, the all-plastic ones you'd suffocate in?" Prove it.

Hit the jump for a video demonstration at a trade show.

Thanks to Sak, who wears a brown grocery bag over his head and wouldn't be able to withstand a rogue can of Progresso New England Clam Chowder diving off the top shelf.
